A machine code arcade game which to my mind closely
resembles Space Invaders.
The enemy space craft progress in formation from the
top of the screen dropping bombs as they go. If you do not
shoot them first they can leave the formation to attack you.
Movement to left and right is controlled by the joystick and the
fire button shoots the missiles. There is nowhere to hide on the
screen. You must keep on shooting and running until all your lives
are lost.
The aliens come in three varieties. The score for each is doubled
if you can hit it once it has left the formation.
Bonus points are awarded if a formation is completely destroyed.
Another wave then appears. An extra ship is gained for every six
convoys destroyed.
The screen display is adequate if unexciting. One of the aliens
looks to me like a flying bowtie. The game loaded without any
problems. The packaging is elaborate and concise instructions
come in a small booklet.
A reasonable game of Space Invaders but I have seen more
interesting versions.
